Video buffers fully use progressive download | Scene7

Issue

Why is it necessary that our mp4 video files are fully buffered when played in our video player? How do I know if the moov atom is placed at the end of the file? How do we correct that when encoding?

This issue occurs when you use Adobe's old-style progressive video download. Instead, use HTTP or RMTP streaming.

If it's necessary to continue using progressive video delivery, take the master (source) video and upload that to SPS. Providing it is a supported input format, SPS can make different video sizes depending on your defined setup, and uses a reliable codec and format.

Here is some info about moov atom (http://www.adobe.com/devnet/video/articles/mp4_movie_atom.html)
“Unless specified otherwise, the moov atom is normally stored at the end of the file in on-demand content, after all of the information describing the file has been generated. Depending on the type of on demand delivery method selected—progressive download, streaming, or local playback—the location will need to move either to the end or to the beginning of the file.”
